B4J Question launch jar application from the menu

Erel said:

Better to use jShell.

You can find the path to java executable with:

B4X:

Dim javaExe As String = File.Combine(GetSystemProperty("java.home", ""), "bin/java")

hanks Erel, but I need to send a string to the main opening of the application that I launch

            Dim shl As Shell
            shl.Initialize("shl", "java", Array As String("-cp", "aps.jar", "b4j.example.main", "http://www.b4x.com"))
            shl.WorkingDirectory = File.Combine(File.DirApp,"plugins")
            shl.Run(10000) 'set a timeout of 10 seconds
            StartMessageLoop 'need to call this as this is a console app.

1. -cp = ?
2. aps.jar = application that I launch
3. b4j.example.main = ?
4. http://www.b4x.com = ?

Have you tried the following to run your aps.jar

B4X:

...
shl.Initialize("shl", "java.exe", Array As String("-jar", "aps.jar"))
...

As regard your other query in post #6

1, -cp classPath - tells java where to look for referenced libraries or jars
3, just a parameter that the example needed. (looks like the entry point into the jar)
4, just another parameter

Spero siano fasulli ma si vedono il tuo indirizzo ed il tuo numero di telefono.

I hope they are fake but you can see your home address and phone number.

Closing the child process shouldn't affect the parent process. I guess that you are doing something wrong in ProcessCompleted event. Check the logs for errors.
